Leadless Pacemaker Registry: Outcomes and Follow-up From the University Hospital of St. Pölten

The registry for leadless pacemakers will collect and annually analyze the data of all leadless pacemaker implantations at the University Hospital St. Pölten, including demographic information, indications, procedural details, acute, medium- and long-term complications during follow-up. Due to the partially novel nature of the signals (atrial mechanical sensing markers) and the lack of long-term experience to date, data on these aspects will also be collected and analyzed. This is a single-center, prospective and retrospective registry that includes all patients receiving a leadless pacing device, as well as all patients who received a leadless pacing device between January 2021 and the start of the registry. All patients undergoing implantation of a leadless pacemaker will be invited to participate in the registry. For patients to be included retrospectively, participation in the registry will be offered at the time of their next routine follow-up visit. The indication for leadless pacing will be determined by the physician responsible for the patient. Enrollment in the registry will in no case alter or influence the treatment the patient receives. Data collection will take place at the time of implantation and continuously during follow-up over the entire study period. Pacemaker-related data may be obtained either in person or via remote monitoring.
